Identification #

Lobarina scrobiculata is a tan to grayish lungwort which appears very similar to Lobaria hallii. When the thalli are dry, L. scrobiculata is usually a more tan, sometimes almost golden or yellowish color compared to the grayer thalli of L. hallii. When hydrated, both species can appear gray and can be nearly identical in appearance. The soralia of both species can be ring-shaped to hemispherical. The lower surfaces of the lobes of the two species can help distinguish them. In mature specimens, L. scrobiculata will not have hairs at the very edges of the lobe undersdies while L.hallii will have hairs which extend to the edge of the lower surface (see photos) (Brodo et al. 2001).
